SPECIFICATION. forming part of Letters Patent No. 760,094, dated May 17,1904.

Application filed January 5, 1904.

To all whom it may concern:

Be it known that we, ROBERT U. WOLFE, CHESTER T. MARTIN, and J AMES E.HANDLIN, citizens of the United States, residingat Lead, in the countyof Lawrence and State of South Dakota, have invented a new and usefulCopy- Holder, of which the following is a specification.

This invention relates to copy-holders for compositors, linotypeoperators, and copyists generally.

The object of the invention is to provide in a copy-holder of thetype inwhich the copy is wound upon a roller as it is copied improved means forsecuring the copy upon the roller, improved means for imparting movementto the winding-roller, and a novel form of screen adapted to serve thedouble purpose of indicating the line to be copied and concealing fromthe view of the operator all other matternot previously copied, and sorelieving the eyes of theoperator of any unnecessary strain.

With the objects above mentioned and others in view, which will appearas the invention is fully disclosed, the same consists in an improvedform of copy-holder, as hereinafter fully described, illustrated inpreferred form in the accompanying drawings, and having the novelfeatures thereof clearly pointed out in the appended claims, it beingunderstood that changes in the structural details may be madewithoutdeparting from the spirit of the invention or sacrificing theadvantages thereof.

In the drawings, Figure 1 is a perspective view of the copy-holder inuse, the movement of some of the parts being indicated by dotted-linepositions. Fig. 2 is avertical section through the copy-holder aboutmidway between the ends. Fig. 3 is an end view of the winding-roller,showing the mechanism for releasing the gripper.

Referring to the drawings, in which corresponding parts are designatedby similar characters of reference in the several views, F designatesthe frame of the copy-holder, which comprises a member 1, formed,preferably, of

Serial No. 187,827. (No model.)

iron or steel and having the ends 2 2 bent substantially at right anglesto the main portion thereof to form brackets for the windingroller,plates 3 3, rigidly attached to the ends 2 2 of the member 1, and plates44, firmly secured upon the ends of the plates 3 3. The end portions 2 2of the member 1 are slotted, as shown at 5 5, to receive the shaft 6 ofthe winding-roller, which extends through openings in the plates 3 3,secured upon the ends of the member 1 by screws or other suitablefastening members, as shown. At one end the shaft 6 has rigidly attacheda knurled disk or hand-wheel 7 to impart rotary movement to thewinding-roller R, and at the other end a ratchet-wheel 8 is rigidlyattached to the shaft and is designed to serve in connection with a pawland operating mechanism to impart movement to the roller when such amechanism is preferred to the hand-wheel above mentioned. The mechanismemployed in connection with the ratchet 8 comprises an arm 10, which isloosely journaled upon the shaft 6 adjacent to the ratchet, a pawl 11,pivotally mounted at one end of said arm and adapted to engage theratchet-wheel, a spring 12, which exerts a downward pull upon the end ofthe'arm carrying the pawl, a stop 13, to limit the pivotal movement ofthe arm upon the shaft, a pivoted member 14, arranged at the bottom ofthe plates 4 and constituting a key for operating the pawl-carrying arm,and a connecting-rod 15 for imparting movement from the key to the arm10.

The gripping mechanism upon the windingroller comprises a rod 16,extending longitu dinally of the roller and disposed in a groove 17,formed in the outer surface thereof, a gripper-plate 18, rigidlyattached to the rod, aspring 19, mounted upon the roller in a recess 20and having the end thereof engaging the outer surface of the plate 18,and mechanism at one end of the roller for turning the rod 16 andforcing the plate 18 out of contact with the roller. The rod 16 isjournaled in disks 21 at the ends of the winding-roller, and an arm 22is rigidly attached to one end of the rod 16 external to the adjacentplate 18. A knurled disk 23 is journaled on the shaft 6 betweenthe arm22 and the adjacent end of the member 1, and studs 24; and 25 areprovided upon the inner face of the disk 23. The stud 24 is at-asuitable distance from the center of the disk to engage the armvv22 nearits inner endwhe'n the'disk 23 ismoved in the direction indicated by thearrow in Fig. 3, and when brought into contact with the arm in thismanner a slight rocking movement is imparted to the rod 16, forcing theplate 18 outward against the pressure of the spring 19. to permitintroduction ofpapers between the plate and the roller or to enablepapers to be removed from the roller. The stud 25 is adapted to contactwith the arm 22 when the arm has been turned sufficiently to cause theplate 18 to swing outward from the roller to the required distance, andthe contact of the stud 25 with the arm stops the forward movement ofthe disk 23 and prevents the stud 24% from passing out of engagementwith the arm. The movement of the disk 23 by which the stud 24 is causedto swing the arm 22 to move the gripper-plate 18 out of operativeposition is directly opposite in direction to the move: ment imparted tothe winding-roller in winding the copy thereon as the copying iscompleted. Consequently the ratchet and pawl associated with the winding.roller to impart rotary'movement thereto will holdthe roller againstmovement under the influence of the disk 23, so that the slidingmovement of the disk 23 will produce only the desired effect upon thecopy gripping mechanism without reversing the movement ofthewinding-roller.

preferably,of light, sheet metal and pivotally 1 mounted upon a rod 27extendingbetween the plates 4; 4:, as shown. erably provided at its freeedge with a plurality of slots28, approximately an inch in depth, whichpermit the operator to see when he has approached the end of his copy,and at the middle pointof the free edge a notch 29 is formed for thepassage of the spring 19, which holds the gripper-plate in operativeposition. As may be seen in Fig. 1, the edge of the screen 26 isparallel to the axis of the shaft 6, and when the copy is evenly woundupon the winding-roller the edge of the screen will be parallel to thelines of the copy. In order to The screen 26 is pref In order to supportthe copy-holderin convcnient position relative to the compositorstype-case or the linotype or type-writing machine by means of which thecopying is to be done, a block 31 is preferably secured upon the rearsurface of the supporting member 1,

and a clamping-bolt 32 is extended through the block for engagement witha bracket B of any preferred construction.

. then imparted to the winding-roller by means of the knurled disk 7 orthe latch mechanism at the other end of the roller to wind the copy uponthe roller until the first line thereof ap pears above the free edge ofthe screen 26. The line thus exposed is then copied, and movement isthen imparted to the roller to bring the second line into view above theedge of the screen, When the hnes correspond in' width to one or moreteeth of the wheel 8, the

.duced by turning the disk 7 by hand. Vhen the copyingis.completed,'the'removal of the copy from the. roller maybe quicklyaccomplished by swinging the pawl 11 out of contact with theratchet-wheel 8 and pulling upon the end of the copy. The pawl being outof contact with the ratchet-wheel, there is nothing to interfere withthe reverse rotation of the roller and the copy will be allowed'tounwind freely until the gripping-plate 18 is uncovered, when the pawlwill be swung again into engagement with the ratchet-wheel, and

the disk 23 will be given a slight turning movement upon the shaft 6 toeffect the release of the copy from the gripof the plate 18.

It will be noted that the copy-gripping plate 18 extends acrosssubstantially the entire width of the copy, so obtaining a firm holdupon the copy and preventing any tendency to tear the copy, while at thesame time insuring the proper position of the copy upon thewinding-roller. The mechanism by which the copy is released from thewinding-roller is of very simple character, may be instantly operated,and cannot become disarranged. It will also be noted that the portion ofthe copy exposed to View at any time comprises only the line to becopied and a few lines of the matter already copied, thus reducing to aminimum the surface exposed to view, indieating clearly and positivelythe line to be copied and lessening the strain upon the eyes of thecopyist. The indicator being provided with the slots 28 at its free edgeenables the operator to tell when he is approaching the end of his copy,so that the arrangement of the lines in the transcript may be determinedaccordingly.

The entire structure of the copy-holder is of such character that it maybe used indefinitely without appreciable wear upon any part thereof andwithout liability to derangement of any portion of the mechanism. Allparts of the copy-holder except the body of the windingroller, which ismade of wood or other light material, are formed of metal in order toobtain sufficient strength without great bulk. The device is generallyattachable to a compositors type-case, or it may, if preferred, besupported upon a bracket mounted upon a type-writer or linotype-machine.If preferred to mount the copy-holder independently of the type-case orthe machine operated by the copyist, a suitable pedestal may be employedin lieu of the bracket B, and the clampingscrews will enable the holderto be secured in any desired position.

The operation of the copy-holder with an ordinary copy has been clearlyexplained in the foregoing pages; but the adaptation of the copy-holderto the display of short pieces of copy which could not be secured uponthe winding-roller quickly enough to justify their arrangement in theordinary manner has not been brought out. The spring 80, which holds thescreen 26 in contact with the windingroller, forms means for effectivelysupporting short pieces of copy,-as the spring can be instantly drawnforward from the screen 26 and the copy gripped by the spring when thecopy is introduced between the spring and the screen and the spring isreleased. The use of the copy-holder in this manner will result in avery material saving in time when an operator has to set up a number ofshort pieces of copy, as the time necessary to secure the several piecesunder the clamping-plate 18 and then bring each piece of copy intoposition to expose the first line thereof above the screen is saved.
